PX560 is indeed a rather unique offer. I think Casio really tried to make a perfect product, it's compact, with whole range of keys, it has assignable knobs, a touchscreen, accompaniment, speakers, inputs and outputs, and a lot of parameters can be easily adjusted. And it sounds good, too.

My fear is that it might be a case when being perfect is not enough. I can imagine that an average customer is not ready to appreciate all these benefits. So Casio went other way with PX-S3000, it is just as simple as possible.

I would grab one of PX560 as well, maybe some day I will; for now I just have to go with my priorities very carefully.

Congrats on your acquisition!
